Applied Technology Group (ATG)

The purpose of the Applied Technologies Group (ATG) is to be responsible for the creation and maintenance of the trade, business and administration document structures that are based on a specific technology or standard. The function of the ATG is the design, assembly and production of syntax specific solutions based on identified business and/or technical requirements from the empowered groups of UN/CEFACT.

Membership is open to experts with broad knowledge in the area of various implementation syntaxes, protocols and mechanisms for the packaging of data for exchange, the functions of UN/CEFACT, and its groups. In addition Heads of Delegations may invite technical experts from their constituency to participate in the work. Experts are expected to contribute to the work based solely on their expertise and to comply with the UN/CEFACT Code of Ethics. [N.B. This text is subject to approval by the UN/CEFACT Plenary]

Two working groups have been formed within the ATG, each with its own scope of work and responsibilities.

ATG1 - EDIFACT Syntax Structures is the home for the work formerly done by the EDIFACT Working Group (EWG) T1 Technical Assessment body and will continue to focus on EDIFACT-related work to include development, maintenance and technical assessment responsibility for:

  • UNSM Design Rules
  • UNSM Design
  • ISO/9735


ATG2 - XML Syntax is responsible for the development and maintenance of XML syntax solutions to support the UN/CEFACT work program. This will include:

  • XML schema production based on identified requirements from the XML empowered groups of UN/CEFACT.
  • Develop and maintain procedures and mechanisms to ensure timely and good quality production of the XML syntax solutions
  • Develop and maintain appropriate technical specifications to ensure consistent application of the XML syntax
